----------------------------------------------

Tx for the review and test, Omkar!

bq. It makes sense to remove appAttemptId from request.. thoughts?? backward 
compatibility?
We should do this, but i'll file a separate ticket to keep focus.

bq. However there is a problem if we restart node manager on which AM was 
running during application run. Attaching logs.
Checked the logs. It's an existing bug where MR AM doesn't go away when told 
to. Will file a ticket.

>  - Single code path for secure and non-secure cases is useful for testing,

>  - Having this in non-secure mode will help us avoid accidental bugs in AMs 
> DDos'ing and bringing down RM.
